Endotrichini Hypotiini Pyralini and see text The Pyralinae are the typical subfamily of snout moths (family Pyralidae) and occur essentially worldwide, in some cases aided by involuntary introduction by humans.

Like many of their relatives in the superfamily Pyraloidea, the caterpillar larvae of many Pyralinae – and in some cases even the adults – have evolved the ability to use unusual foods for nutrition; a few of these can become harmful to humans as pests of stored goods.

No quantitative phylogenetic analysis had been done as of 2007, though in the mid-late 1990s Michael Shaffer of the London Natural History Museum and Maria Alma Solis of the NMNH prepared the groundwork for further studies by their comprehensive qualitative reviews of Pyralinae morphology.

Some cladistic studies of the Pyraloidea do exist however, and these place the Pyralinae among the advanced snout moths, a lineage which otherwise includes the even more autapomorphic subfamilies Epipaschiinae and Phycitinae.

[1] Even though the Pyralinae contain a high number of genera and species, there are a mere three tribes generally accepted nowadays; others that were proposed earlier (in some cases even as independent subfamilies within Pyralidae) are presently treated as junior synonyms of the Pyralini.
